How to solve the problem of poor cooling performance of the heat transfer oil circulation system?
Some heat-conducting oil circulation systems will not be as good as before after 3 months of use. At this time, it is recommended to contact the professional after-sales department to check the user's power supply and whether the equipment is normal. The test heat conduction oil circulation system is set to cool operation, and the working pressure is 4.5kg/cm2. Considering that the variable frequency heat transfer oil circulation system uses the electronic expansion valve to throttle, it is n...

How is the electric vehicle battery test driver grounded?
If the electric vehicle battery test is not isolated between the AC power source and the drive DC bus (such as a transformer), do not connect the non-isolated port of the DC bus or the ground of the non-isolated signal to the ground, which may result in equipment damage and personal injury. Because the common voltage of the AC is not to earth, there may be a high voltage between the DC bus ground and the earth. In most electric vehicle battery test systems, all common ground and earth are con...

Characteristics of the evaporator of LNEYA screw chiller
The amount of cooling capacity of the screw chiller is directly related to the energy consumption and operational economics of the entire unit, which is worthy of attention. Especially when designing a cold station, there is no single chiller in the general situation. This is mainly because when the screw chiller fails or is shut down for maintenance, it will not stop production. Instead, the reasonable unit should be selected according to the production situation. The number of units. When t...

Factors affecting cooling capacity during temperature control of battery test equipment
Battery Test Equipment Refrigeration System The greater the power of the battery test equipment compressor, the higher the cooling capacity. According to the size of the battery test equipment, the compressors of different types are selected. For example, the small battery test equipment is piston type, and the medium type is optional. Scroll type. When the water temperature of the battery test equipment (the evaporation temperature is different, the cooling capacity is different), the higher...

Importance of refrigerants in new energy vehicle battery test systems
If the flow rate of the refrigerant in the new energy vehicle battery test system is extremely small, the refrigerant will start to expand from the first expandable space at the rear end of the throttle valve. Most of the see-up of the rear end of the expansion valve is often due to lack of cooling. Or the expansion valve flow is not enough, too little refrigerant expansion will not use all the evaporator area, only the low temperature is formed locally in the evaporator, and some areas are r...
